Variable interaction with different animation layers?

Question

Unity

There are two layers of animation

- the base layer is responsible for the "planet" disappearing - the second one is for launching the display of asteroids (space theme of the scene)
Base layer

The second layer

in both layers - the transition condition from NewState - to another state - this is a boolean variable P - must be
true I change the value of the variable - it works on pressing the button

public void Load()
    {
        var animator = planet.GetComponent<Animator>();
        animator.SetBool("p", true);
    }

The most interesting thing is that in the inspector - changing the variable is not displayed - but the effect on one of the animations - the one that disappears the planet - works, and the second animation - on the second layer - does not work. And only when I manually in the inspector - set the value to true - the second animation is triggered - the one on the secondary layer.
That is, it is strange that the value is apparently still set to true - once the first animation is triggered, but why the change is not displayed in the inspector and the second animation does not work is not clear.
